A little more polish and I'll post the link tomorrow

It's been a while since I've gotten to play with html, css, and svg.

Learned something neat with this too. I highlight a line set with a gradient when you mouse over the line below. Sometimes a line would disappear. Turns out, if you have a vertical or horizontal line the renderer will see them as 0px wide/high and not draw them. A .001 offset fixes it :)

There's an addon for Chrome called "F.B. Purity". I highly recommend it :)
